Abstract
The clay mineralogy of a sequence of 36 andesitic tephra and associated paleosols dating from 320 to > 100,000 years BP has been studied using XRD, IR, DTA and TEM techniques. The mineralogy and weathering sequence is compared with that of rhyolitic tephra of central North Island, New Zealand.Keywords
